Suburb risk flags
crime index: 25 — below sydney average
Where every number comes from
- Fair value: AI PropertyEye price model 2026-08-11-v5 — trained on 146,492 published auction sales; configuration-level (suburb × type × beds), not an appraisal of this exact home
- Risk flags: suburb-level overlays (BOCSAR crime, flood/bushfire intel, aircraft bands, GTFS transit) — NOT a per-parcel assessment
Local rents — postcode 2099 units, new tenancies
$820/week median new-tenancy unit rent in 2099 (2026Q2, 312 bonds lodged).
The rent is real (NSW Fair Trading bond lodgements, CC BY) but it pools every bedroom count in the postcode and this is a 3-bed — so we don't derive a yield % from it: a ratio of two different grains reads as precision it doesn't have. New-tenancy rents also run hotter than sitting rents. Not financial advice.
Growth trend — Dee Why units at auction
Measured like-for-like growth ≈ -2.1%/yr — 2-bed sold-price medians across 17 quarters (130 sales).
Suburb-level, from published auction results. No single building has enough sales for a block-level series, so this is the honest grain; sales-mix shifts move raw medians, and the measured rate (when shown) controls for bed count.

Planning & zoning — MU1 Mixed Use
Shops/offices below, apartments above. Walkable and lively, but denser and busier.
Registered lot 2/DP1241568 · ~13,209 m² — The registered plan lot at this address's geocoded point (NSW cadastre). On semis, duplexes and recent subdivisions the registered lot can be the parent parcel — the portal's advertised land size can differ legitimately.
Registered lots in Dee Why run 360–1,110 m² (middle 80% of 23 registered parcels). This one is 13,209 m² — above that range.
Whether a block this size can be subdivided or redeveloped is a separate question: minimum lot size, setbacks and the council's DCP controls decide it, and this page doesn't check them. One point per registered parcel, so a tower's parent lot counts once — not once per unit. Confirm the parcel and its controls with the council before you inspect.
Zone MU1 (Mixed Use) under the NORTHERN BEACHES LEP, from the NSW ePlanning layers at this address's geocoded point — a guide, not a parcel-level legal check. Confirm the exact lot at the NSW Planning Portal.

Matched at this exact address or within ~150 m of its geocoded point — proximity evidence, not a parcel-level check. Lodged means proposed, not approved or built. Outcome comes from a separate NSW dataset that stops in Nov 2023: applications determined after that, or still undetermined, read “not on record” — which means we don't know, never that it was refused. “Status” is the council's own workflow state and “Determined” on its own does not say which way it went.

Construction risk — what no listing tells you
Building Commission NSW / Strata Community Association 2023 Strata Defects Survey: 53% of newly registered strata buildings reported at least one serious defect in common property (39% in the 2021 survey). Defects are common, not exceptional — and new does not mean safe (Opal Tower was under a year old).
Get an independent structural and strata inspection before you commit — the defect base rate makes it the single highest-value dollar in the purchase.
We cannot see inside a building — no one can from public records. This section states base rates and observable adjacency only, and will never call a building safe.

Protected public recreation land within 100 m
Land zoned RE1 under the local environmental plan — reserved for public recreation, which protects it from being built over. The zoning doesn't say what's on it or how usable it is, and this layer doesn't carry park names.
Privately-zoned recreation land (RE2 — typically golf courses or club grounds) within 2000 m. Private land: green outlook, not public open space.
